Cena got "boring" chants because he's been pushed down the audience's throats for 9 years now with the same exact character, same schtick. Just like people last week were wondering how Cena would act this week after showing heel tendencies last week. Well, he reacted by being the same old John Cena, laughing and smiling everything off. That's why he got "boring" chants. He's become a chariacture of himself now. He's a joke and has been for awhile. Those "boring" chants were glorious, and he had no idea how to react which is why he got that awkward smile. It was awesome. Goat, my ass.
